This paper reports on lepton flavor violating rates that can be experimentally measurable even if the observed neutrinos are strictly massless. We make a study of the attainable rates for anomalous leptonic muon and tau number violating decays such as {mu} {yields} e{gamma}, {mu} {yields} 3e, {tau} {yields} {mu}{gamma}, {tau} {yields} e{gamma}, {tau} {yields} {mu}{mu}{sup +}{mu}{sup {minus}}, {tau} {yields} ee{sup +}e{sup {minus}}, {tau} {yields} e{mu}{sup +}{mu}{sup {minus}}, etc. as well as semileptonic lepton flavor violating tau decays such as {tau} {yields} {mu}{pi}{sup 0}, {tau} {yields} e{eta}, etc. All muonic violating decays can be as large as the present limits from LAMPF, TRIUMF and PSI. The corresponding tau violating processes can all be at the limit of sensitivity of the upcoming {tau} factories.
